[PATCH net v2 1/1] net: stmmac: Add queue reset into stmmac_xdp_open() function

Queue reset was moved out from __init_dma_rx_desc_rings() and
__init_dma_tx_desc_rings() functions. Thus, the driver fails to transmit
and receive packet after XDP prog setup.

This commit adds the missing queue reset into stmmac_xdp_open() function.

v2: Add reviewed-by tag
